The Living Room's Barry Du Bois reveals his cancer has returned for second time

The lifestyle expert, who hosts Network Ten's The Living Room, revealed on Friday's episode that he is now facing cancer for the second time.

Barry, 57, was first diagnosed with plasmacytoma myeloma, a cancer attacking health bone marrow, in 2010. Growing tearful, he explained to his co-panel that his cancer has returned as a more aggressive form known as multiple myeloma that has "created several tumors right through my body," he said.

"In the medical world, I am on the exit off the freeway, there is no doubt about that," he added.

"I have always backed myself and I will back myself on this and I will have the support to win it."

He also took to Instagram to share his diagnosis with his fans. Sharing a photo of himself with his Living Room family, he wrote: "I am sure my announcement on The Living Room tonight that my cancer has returned was a shock for many of you."

"After living six years in remission, it was a shock for my family and I too," wrote Barry, who shares twins Arabella and Bennet with wife Leonie.

"The Living Room means more to me than most things on Earth, and it means an incredible amount to be loved by so many people. Thank you so much for all your love and support. It means the world to me.

I am going into this battle with the love, support and encouragement of my friends and family, and all of you. I'm going to beat what I have got, and hopefully inspire others to do so too," he concluded.

In an interview with The Telegraph, he revealed he has began chemotherapy, which he expects to complete by Christmas, and will undergo a stem cell transplant and bone marrow retrieval.
